I have a brass hunter 18 size case. I would like to put a 15 jewel Columbus in it. I can polish it but keeping it polished is the problem I have. I don't want to have to polish it every week or so. Is there any kind of coating you can put on a brass case to keep it from tarnishing? Can you put a clear coating of some type a paint?

I haven't used this method on a watch case, but brass furniture (lamps, bed railings, planters. etc.) are commonly protected with a sprayed-on coat of lacquer or similar clear topcoating. It eventually deteriorates from atmospherics, and wears off from handling abrasion -- but it protects the shine and color of the underlying brass MUCH better than leaving the metal naked. However, spray application would be tricky, requiring very good equipment and a skilled hand to avoid runs/bubbles/gumming up hinges, and clogging the stem opening. If that's not in your skill set, I would suggest looking for a custom auto or motorcycle painter who's used to using small airbrush sprayers to lay down custom designs.
Good luck!

I have used clear spray lacquer to coat the brass dial rings on my antique Seth Thomas clocks. It is made by Testors, commonly used to spray model cars. You should be able to find it in craft or hobby stores. I am going to attach a link of my clock to this post.
Thank you Damien and Steve I new brass furniture and the like had a clear coating but did not know if it could be put on these old cases. I was not sure of the process. I will give it a try. Thanks guys!
Also Steve you did a great job on that Ball clock!

Fantastic job on the case restoration, Steve. And the work on the dial is remarkable. If I'm ever in Cleveland again for a WWT or something I'd like to see it in person.
Harry, try WD-40.

I use Blue Magic Metal Polish Cream. You can find it at most auto parts stores. It hand buffs nicely and leaves a thin protective coat. The shine won't last forever but I find that without an air brush spray lacquer tends to have a mind of it's own. If you do use the spray can lacquer I would be very interested in your results.

The spray can stuff tends to be a bit glorpy ( my official definition of glorpy is that the spray is not fine enough) as those spray nozzles aren't the best. If you know someone with an airbrush you will probably have a better result.
The beauty of lacquer however is that you can wash it all off with lacquer thinner and start over.
